Wrong name of the global symbol in LinkerScript part #6

Open oliwkowemango opened 5 years ago

oliwkowemango commented 5 years ago

This script tells the linker that the program's entry point is at the global symbol _Entry, which we export from startup.s.

Should it be a _Reset instead of _Entry?

@oliwkowemango

yes, you're right. You can see that it actually uses _Reset in the linker script:
